Used as an insult. If you say someone is ‘spare parts’ then you’re calling them useless, or they’re so poor at what they are doing that they might as well be doing nothing.
In a co-op video game, if there’s someone in your party that ends up doing jack shitfor the team, then you’d say they are “spare parts.”
Player 1: Dude, player 3 got no absolutely no kills the entire round.
Player 2: I know, right? He just sat on his ass the whole game!
Player 1: Yup—he’s spare parts.
